Title: Method and device for plasma treatment
Inventor: TAKAHASHI NUSHITO
IPC: H01L21/302
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To obtain uniform treatment characteristics in a substrate surface by maintaining uniformity in the surface of a side wall protection film being formed on the side wall of a part to be etched of a substrate to be treated for plasma treatment. SOLUTION: The efficiency of the exhaust of a reaction product in a plasma-treating device becomes better toward the outer periphery of a substrate. When the temperature distribution of the substrate is uniform in a surface, the density distribution of the reaction product in a gaseous phase is high at the center part of the substrate and is low at the periphery part. For the relationship between pressure Pa of the rear surface of the substrate and heat passing rate (W/m<2>  deg..K) due to a gas molecule, the higher the pressure of the rear surface becomes, the greater the heat transmission rate becomes, thus obtaining the relationship between the distance (d) from the rear surface of the substrate to the surface of an electrode and the heat transmission rate due to the gas molecule.  Therefore, the depth (d) of recessed parts 34, 35, and 36 of an electrostatic attraction electrode surface is changed from the center toward the outside for increasing the temperature of the center of the substrate, thus changing the adsorption probability of the reaction product in the substrate surface, and hence making uniform the amount of adsorption of the reaction products being used as a side-wall protection film uniform.

IPC: G06T5/20
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To smooth a complicated multi-dimensional image by making each point pass through a recursive space filter which performs smoothing of a large degree in a direction that is perpendicular to the direction of luminance gradient more than the direction of the luminance gradient. SOLUTION: Image smoothing is executed by recursive space filtering so as to compress noise. A coordinate system of an image for automatic scanning is defined in a priori due to the smoothing of an image to be processed. The coordinate system is stored, e.g. in a memory 630. In the case of a three- dimensional image and a two-dimensional image, a coordinate system for scanning that is defined in the same manner as a coordinate system of a gradient angle for discretization is shown. Thus, in the case of the three-dimensional image and the two-dimensional image, a set of directions of scan lines which are mutually parallel and are shown in such manners as ψ,j and ψj is defined on a CFC coordinate system and an image flat plane. Each set of scan lines extends in parallel with respective discrete directions θ'j and θj of gradients.  The discrete directions θ'j and θj of gradients are shifted by 180 degrees.
